Cockpit Display Partitioning With Compressed Ethernet Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of cockpit systems due to high image bandwidth requirements between the head unit and display system, which is exacerbated by large and high-resolution automotive panels, necessitates a reduction in image bandwidth to simplify system complexity.
Innovation Solution
An electronic device with a processor circuit and display device featuring separate ports for receiving and processing data signals, where the second image signal is compressed using video coding standards like H.264 or H.265, transmitted via automotive Ethernet, and displayed in a touch-enabled second region, allowing the head unit to generate first image content locally and reducing bandwidth demands.

Engineering Contradiction Analysis
1Manufacturing precision
If large size and high resolution automotive panels are used to improve display quality, then display performance is improved, but image bandwidth requirement increases and system complexity increases
Solution Approach 1:
The display system is segmented into multiple independent display regions (first display region for instrument cluster, second display region for infotainment) with separate processing paths. Each region has its own image signal processing chain, allowing independent optimization and reducing the complexity of processing the entire display at once.
Solution Approach 2:
The patent applies image compression algorithms (H.264, H.265) to reduce the bandwidth requirement of image signals. By changing the parameter of image representation from uncompressed to compressed format, the data transmission requirement is significantly reduced while maintaining display quality.

By changing the parameter of image representation from uncompressed to compressed format, the data transmission requirement is significantly reduced while maintaining display quality.
Solution Approach 2:
The patent extracts and processes different image signals for different display regions separately. The first image signal is generated locally by the processor circuit, while the second image signal is received from external sources, allowing optimized bandwidth allocation for each region's specific requirements.
3Adaptability or versatility
If cluster display and central information display are combined to form cockpit system, then display functionality is improved, but image bandwidth and system complexity increase
Solution Approach 1:
The combined cockpit display system is segmented into functionally independent first and second display regions, each with separate image signal processing paths. This segmentation allows each region to be optimized for its specific function while reducing the overall system complexity through modular architecture.
Solution Approach 2:
The display device is designed with multi-functionality to serve both instrument cluster and infotainment purposes through a single integrated display panel with multiple independent display regions, reducing the need for separate physical displays while maintaining functional independence.
